Article 4 Acknowledgment of receipt of a complaint and verification of its admissibility
Summary What does Article 4 of the RTS on CASP complaints handling say?
This article governs the initial response obligations of crypto-asset service providers once a complaint is received.
It builds directly on Article 1, which establishes the admissibility conditions and timeframes that complaints-handling procedures must contain.
The article covers two scenarios: what happens when a complaint is accepted, and what must be communicated when it is rejected as inadmissible.
For accepted complaints, the acknowledgment of receipt must include a specific set of information to ensure the complainant knows who is handling their case and what to expect next.
Important points:
- Acknowledge receipt of every complaint and confirm its admissibility without undue delay.
- Where a complaint is rejected as inadmissible, provide the complainant with a clear explanation of the reasons for that rejection.
- Ensure every acknowledgment of receipt includes contact details of the responsible person or department, the date of receipt, a reference to the applicable timeframe, and, where applicable, a copy of the electronically filed complaint.
Springlex's summary of the article, a reading aid, not a substitute for the legal text.
Crypto-asset service providers shall acknowledge receipt of a complaint and inform the complainant about whether the complaint is admissible without undue delay after having received the complaint.
Where a complaint does not fulfil the conditions of admissibility referred to in Article 1(2), point (a), crypto-asset service providers shall provide the complainant with a clear explanation of the reasons for rejecting the complaint as inadmissible.
The acknowledgment of receipt of a complaint shall contain all of the following:
The name, identity and contact details, including email address and telephone number, of the person to whom, or the department to which, complainants can address any query related to their complaint;
the date of receipt of the complaint;
a reference to the timeframe referred to in Article 1(2), point (e);
where an electronic complaint form is filed, a copy of the complaint.

Recital 4 Timely acknowledgement and admissibility checks
To ensure a prompt and timely handling of complaints, crypto-asset service providers should acknowledge receipt of complaints and inform the complainant as to whether that complaint is admissible without undue delay. Upon acknowledgment of receipt of the complaint, the complainant should also receive the contact details of the person or department to be contacted for any queries related to the complaint, as well as an indicative timeframe within which a decision on the complaint can be expected. Where a complaint has been found to be inadmissible, the crypto-asset service provider should inform the complainant of its decision and provide the complainant with the reasons for the inadmissibility.
